Moderate sample. 433 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 1998 Land Rover 90 Defender TDI has a first-time MOT pass rate of just 10.3%, far below the UK average of 80%—this is a seriously unreliable cohort on paper. However, the absence of dangerous defects (0%) and the minimal average of 0.24 failures per vehicle suggests that most failures are relatively minor and fixable rather than structural safety issues.

These vehicles are running at 140,713 median miles, which is typical for their age, so high mileage isn't the main culprit here. The real story is that these old Defenders are temperamental in their dotage; they'll need frequent small repairs to pass MOT, but they're not death traps—if you buy one, budget for a pre-purchase inspection and expect to throw money at it regularly rather than face one catastrophic failure.

The 1998 Land Rover 90 Defender TDI passes its MOT first time at roughly the UK average rate (76.2%) — solid but worth checking this vehicle's history carefully.
